The only LLM-Based Experience^tm^ I've had so far (and probably ever) was a brief session of Death by AI I had with friends, and that game boils down to "give the chatbot a prompt and your response, and maybe try to not die horribly".
Pretty much all the fun of that game comes from giving the chatbot manmade horrors beyond its comprehension and seeing it struggle to keep up.
Novelty value is basically the only thing LLMs have going for them, and that isn't changing any time soon.
